IMPROVED CARPENTERS GAGE.

Specification forming part of Letters Patent No. 11,572, dated August22, 1854.

To all whom it may concern.

Be it'known that we, HALCYON'SKINNER and WILLIAM GREENHALGH, of WestFarms, in the county of Westchester and State of N ew York, haveinvented a new and useful Improvement in Combination-Gages; and we dohereby declare that the following is a full and exact descriptionthereof, reference being had to the annexed drawings, forming a part ofthis specification, in Whichi f Figure l is a side View of ourimprovement; Fig. 2, sectional view of the same; Fig. 3, view of anotherside; Fig. 4, View of side opposite Fig. 3; Fig. 5, horizontal section;Fig. 6, perspective view.

Similar letters refer to like parts.

a is the frame of the instrument; b, fixed fence; c, gage-point; d,sliding fence; c, ad-

justing-screw; f, sliding gage-bar; g, sliding -fence; h,adjusting-screw; t', sliding fence; k,

sliding gage-bar; Z l m, gage-points; n, shoulder; o p, gagejpoint.

Our invention consists in the combination, into one convenientinstrument, of several sliding adjustable gages, so arranged thatvarious operations in carpentry hitherto requiringthe employment ofseveral distinct and costly instruments may all be accomplished by theuse of one of our improved gages.

In constructing our gages we make a grooved and slotted frame, a, in theform shown in the various figures. At the lower end of the frame a weattach a fixed fence, b, having a gagepoint, c, placed in the center ofone side. The other extremity of the frame a is furnished on both sideswith gage-points l l. The sliding fence d is made to fit the groove andslot of the frame a, and has a shoulder, n, which projects through theslot in the frame a to an even On this opposite side there is agagepoint, o. rlhe sliding gage d and gage-point o are adjusted andsecured in any desired position by means That portion of the of the adjustin gscrew e.

groove in the frame a above and on lthe same side with d lis occupied bythe sliding fence g and the sliding gagebarj'. The sliding gagebar f isslotted throughout its entire length, and occupies the inner or centralportion of the groove. The sliding gage-bar f is armed at its upper endwith a gage-point., 19. The sliding fence g is also slotted and movesupon and outside of f. 0n the opposite side of the instrument there isanother sliding gage-bar, It, with point m, arranged and moving in thesame manner as f. There is also another sliding fence, fi, arranged andmoved in 'the same manner as g. The sliding fences g i and the slidinggage-bars f k are all adjusted and secured by one adjusting-screw, e.The various gage-points are so 'inserted that they can at any time bepushed out or removed `Whenever they become Worn.

It is needless for ns to specify the various ways in which ourimprovement is useful in carpentry, since every carpenter will readilyrecognizeits advantages. It may at all times be used in place of theordinary gage., and also in place of all other double or special gages,since it combines the advantages of the Whole of them in the mostconvenient manner, besides possessing many more useful qualities not tobe realized at all with the others.`

Our improvement is cheap, durable, and very simple, there being only twoadjusting screws in its entire construction.

Having thus. described our invention, We
